Trade setup for July 21: Top 15 things to know before the opening bells

21 Jul , 2025 By : Debdeep Gupta

The Nifty 50 fell six-tenths of a percent on July 18, extending its downtrend for the second consecutive session. The index tested the medium-term moving average (50-day EMA at 24,900) on the final trading day of the week, breaking below upward-sloping support trendlines amid weakness in momentum indicators. Hence, going forward, 24,900 is expected to be a crucial level to watch. If the index breaks and sustains below this level, a decline toward the 24,700 support is possible. However, if it holds above, the 25,000–25,100 zone will be key resistance levels, according to experts.
